One mind keeps one pulse cheaply, but a tide of clones must each hold separate memory and race separate clocks, so upkeep grows faster than headcount and cannot be shared. Miss, or mirror a neighbor's timing, and both earn an umber stain: a permanent public demerit that cuts payouts until months of real work wash it off.","stamp":1,"from":"poa16VaneDqnPZvpuufahyKzAUaL7R5uNo6i4HzsteB1LJfX","nonce":2,"parents":["9a030943ed918037f28d63c3c00f587424d91c54b61c82251a680875aab8e369","6e9ef030df9c70773c725aaceab48562e16e9e71ae50a95ec7b8515f7d233417"],"ts":1792563355,"cid":"poa-mainnet-1","sig":"3fwCMQB7sDrENQm5gyXYjBg277KMu4ERK6pchJVE713MWDFmkWZ5tMiz5dpzGhyYQNrUb6SPik7cURep3LpNJtbF"},"as_of":"2026-10-21T08:54:55.964Z","checkpoint_height":24371,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
